Managing resources for cooperative uplink transmission

A method for wireless communication by a base station, comprising:

• determining a plurality of UE groups for a plurality of user equipments (UEs) participating in cooperative uplink transmission to the base station, wherein each UE belongs to a UE group of the plurality of UE groups, each UE group having a unique UE group number, wherein at least one operation to be performed by a UE in a Transmission Time Interval (TTI) is selected from a set of operations, wherein the selection is based, at least in part, on a UE group number of the UE group to which the UE belongs and a TTI index of the TTI, wherein a different operation of the set of operations is selected for a different combination of TTI index and UE group number;
• communicating with the UE based on the selected at least one operation;
• and
• transmitting mode configurations indicating whether or not UEs in each group are configured to transmit data as a data source or to relay data received from another UE configured to transmit data as a data source.

An apparatus for wireless communication by a user equipment (UE), comprising:

• means for participating, with one or more other UEs, in cooperative uplink transmission to a base station, wherein each UE belongs to a UE group of a plurality of UE groups, each UE group having a unique UE group number;
• means for selecting at least one operation to be performed in a Transmission Time Interval (TTI) from a set of operations, wherein the selecting is based, at least in part, on a UE group number of the UE group to which the UE belongs and a TTI index of the TTI, wherein the UE is configured to select a different operation of the set of operations for a different combination of TTI index and UE group number;
• and
• means for performing the selected at least one operation for the cooperating uplink transmission.
